Henry Winkler posted a selfie on Twitter Monday, showing him and his former "Happy Days" co-star Ron Howard at the Emmy Awards ceremony in Los Angeles.

"Pals at the Emmys," Winkler captioned the photo, which features him and the Oscar-winning filmmaker dressed in formal wear and smiling.

Howard re-tweeted the picture and added the message: "My friend's win is so deserved and great. ! Bravo @hwinkler4real."

Winkler, 72, won his first Primetime Emmy -- the Best Supporting Actor in a Comedy honor -- for his work in "Barry," which recently wrapped its first season.

"Happy Days" initially aired 1974-84 and has remained popular in re-runs ever since.
